The article presents an innovative technology for finishing wood using ultrasonic treatment, aimed at improving the quality of paint and varnish coatings and reducing the material intensity of the process. The effect of ultrasonic pretreatment on the adhesive and physical and mechanical characteristics of protective and decorative coatings was experimentally studied. It was found that ultrasonic treatment allows reducing the consumption of paint and varnish materials by 18-22% while increasing adhesion by 25-30% and increasing wear resistance of coatings by 35-40% compared to traditional technology. An economic analysis of the implementation of the technology in the production of wooden products was carried out. The technology is of practical interest for the furniture and woodworking industries, ensuring resource conservation and increasing the competitiveness of products.
